Abstract: An automatic transfer switch for power over ethernet lighting and powered devices preferably includes at least one transfer switch module, a carrier board, a power supply and a housing. Each transfer switch module preferably includes a plurality of input transformers, a plurality of output transformers, a microcontroller, a power source equipment device, a power transfer device, a LAN Multiplexer and a PoE power monitor. The at least one transfer switch module is retained on the carrier board. The plurality of input transformers receive power and data inputs from power sourcing equipment. If a backup power switch detects a loss of power, a signal will be received by the microcontroller of the at least one transfer switch module. The microcontroller will instruct the power transfer device to supply electrical power to the plurality of output transformers. Data will also be supplied by the microcontroller to the LAN Multiplexer.

Abstract: The present invention relates to a soil injection apparatus in which a probe having on insertion tip is inserted into the soil. A pair of probe guide assemblies are positioned adjacent each side of the probe to provide stability of the probe and prevent breaking of the probe. A probe hydraulic system extends and retracts the probe from the soil. A liquid pumping system pumps liquid into an outlet of the probe after insertion of the probe into the soil. A control system activates the probe hydraulic system and liquid pumping system. Preferably, a switch is used to activate the pumping system to pump liquid into the soil after the probe has been inserted a predetermined depth into the soil. The soil injection apparatus can be attached to a self-propelled vehicle. A carrier can be attached to the vehicle for holding debris removed from the soil injection site.
